Title: Retaining strip for document letter file - is made by tearing off strip from plastics backing strip
Inventor: STRAETER FRITZ
IPC: B42F11/00
Filed: 1977-05-16
Abstract: A document of letter file has a backing strip made from a sheet of plastics, with holes for attaching it to the file cover and for receiving a strip of flexible plastics (4) which passes through the holes punched in the edges of the documents.

Patent DE-2734391-A1 (DE)
Inventor: RECH WERNER DIPL PHYS DR
IPC: G01N21/21
Filed: 1977-07-29
Abstract: The device serves for the optical detection of suspended particles. The radiation from a source (2) is polarised via a liquid-crystal cell (4) in a temporally periodic fashion in two mutually perpendicular planes ( phi @,  phi  PARALLEL ). The radiation scattered by the suspended particles in the chamber (1) and situated in these planes is used to generate a signal which is proportional to the degree of polarisation of the scattered radiation and depends linearly on the mean diameter @ of the particles. By logical combination (13, 14) of this signal with a signal proportional to the scattered radiation, a signal is produced which is proportional to the product of @ and the number n of particles. The device is applied in display units for suspended particles. <IMAGE>

Title: Padded envelope making appts. - folds and glues two corrugated paper webs differently aligned between two plain paper webs
Inventor: PORTH ERWIN
IPC: B31D1/00
Filed: 1978-05-30
Abstract: The continuous production method for padded bag type envelopes uses two webs of thin paper forming the outer and inner walls respectively with padding material inserted between them.
